Linux kernelUpdated: 12/20/2024 by Computer HopeThe Linux kernel is the foundation of any Linux-based operating system. It represents the core of Linux distributions for servers and desktop computers. It's also used in embedded systems, such as routers, and in all Android-based systems, ...
While they all have the Linux kernel in common, various Linux distributions build their own operating systems on top of the basic open-source foundation. Linux distributions, referred to as “distros,” boast a range of backgrounds and features. Ubuntu is the world’s most popular free OS and...
Kernel Security & Protection The kernel also protects the hardware. If there is no protection, any program will be able to carry out any task on the computer, including crashing your computer, corrupting data, etc. In modern-day computers, security is implemented on the hardware level. For ex...
Rootkit hypervisors– These rootkits exploit hardware virtualization features to gain control of a machine. This is done by bypassing the kernel and running the target operating system in a virtual machine. Hypervisors are almost impossible to detect and clean because they operate at a higher level ...
Kernel mode rootkit.This type of rootkit is designed to change the functionality of an OS. The rootkit typically adds its own code -- and, sometimes, its own data structures -- to parts of the OS core, known as thekernel. Many kernel mode rootkits exploit the fact that OSes allow devic...
However, a kernel rootkit laden with bugs is easier to detect as it leaves a trail for anti-rootkit or antivirus software. These rootkit types have been used to create devastating attacks, including: NTRootkit: One of the first malicious rootkits created, which targeted the Windows OS. ...
What is a Linux Kernel? The Linux kernel is central to the Linux computer operating system. Thekernelis the core interface between a computer's hardware and its processes, making sure there is available memory for Linux applications to run, optimizing processors, and navigating system requirements...
Linux kernel vs. Linux operating system A kernel is a computer program that functions as the beating heart of the OS, the system that allows users to interact with the computer’s hardware and software. In the case of the Linux OS, the Linux kernel is the code that forms the core compon...
In general, the main goal of the rootkits is to hide itself and other modules of the hosted malware on the kernel layer. The rootkits are potent tools but carry a high risk of being detected because the rootkits work in the kernel-mode, and each critical bug leads to BSoD (the Blue ...
What is kernel-level programming in an OS? Kernel-level programming involves writing software that interacts directly with the operating system's core functions (the kernel). This type of programming requires specialized knowledge and can be used to create device drivers, security software, and other...
